Constructor & Destructor Documentation

DcmDate::DcmDate (  const DcmTag &  tag,
const Uint32  len = 0
) 
 

constructor.

Create new element from given tag and length.

Parameters:
tag DICOM tag for the new element
len value length for the new element

DcmDate::DcmDate (  const DcmDate &  old  ) 
 

copy constructor

Parameters:
old element to be copied

Member Function Documentation

OFCondition DcmDate::getCurrentDate (  OFString &  dicomDate  )  [static]
 

get the current system date.

The DICOM DA format supported by this function is "YYYYMMDD". If the current system date is unavailable the date is set to "19000101" and an error code is returned.

Parameters:
dicomDate reference to string variable where the result is stored
Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::getDicomDateFromOFDate (  const OFDate &  dateValue,
OFString &  dicomDate
)  [static]
 

get the specified OFDate value in DICOM format.

The DICOM DA format supported by this function is "YYYYMMDD". If the specified date is invalid the date is set to "19000101" and an error code is returned.

Parameters:
dateValue date to be converted to DICOM format
dicomDate reference to string variable where the result is stored
Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::getISOFormattedDate (  OFString &  formattedDate,
const unsigned long  pos = 0,
const OFBool  supportOldFormat = OFTrue
) 
 

get the current element value in ISO date format.

The ISO date format supported by this function is "YYYY-MM-DD". Please note that the element value is expected to be in valid DICOM DA format ("YYYYMMDD", "YYYY.MM.DD" is also supported for reasons of backward compatibility). If this function fails the result variable 'formattedDate' is cleared automatically.

Parameters:
formattedDate reference to string variable where the result is stored
pos index of the element component in case of value multiplicity (0..vm-1)
supportOldFormat if OFTrue support old (prior V3.0) date format (see above)
Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::getISOFormattedDateFromString (  const OFString &  dicomDate,
OFString &  formattedDate,
const OFBool  supportOldFormat = OFTrue
)  [static]
 

get the specified DICOM date value in ISO format.

The ISO date format supported by this function is "YYYY-MM-DD". Please note that the specified value is expected to be in valid DICOM DA format ("YYYYMMDD", "YYYY.MM.DD" is also supported for reasons of backward compatibility). If this function fails the result variable 'formattedDate' is cleared automatically.

Parameters:
dicomDate string value in DICOM DA format to be converted to ISO format
formattedDate reference to string variable where the result is stored
supportOldFormat if OFTrue support old (prior V3.0) date format (see above)
Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::getOFDate (  OFDate &  dateValue,
const unsigned long  pos = 0,
const OFBool  supportOldFormat = OFTrue
) 
 

get the current element value in OFDate format.

Please note that the element value is expected to be in valid DICOM DA format ("YYYYMMDD", "YYYY.MM.DD" is also supported for reasons of backward compatibility). If this function fails the result variable 'dateValue' is cleared automatically.

Parameters:
dateValue reference to OFDate variable where the result is stored
pos index of the element component in case of value multiplicity (0..vm-1)
supportOldFormat if OFTrue support old (prior V3.0) date format (see above)
Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::getOFDateFromString (  const OFString &  dicomDate,
OFDate &  dateValue,
const OFBool  supportOldFormat = OFTrue
)  [static]
 

get the specified DICOM date value in OFDate format.

Please note that the specified value is expected to be in valid DICOM DA format ("YYYYMMDD", "YYYY.MM.DD" is also supported for reasons of backward compatibility). If this function fails the result variable 'dateValue' is cleared automatically.

Parameters:
dicomDate string value in DICOM DA format to be converted to ISO format
dateValue reference to OFDate variable where the result is stored
supportOldFormat if OFTrue support old (prior V3.0) date format (see above)
Returns:
EC_Normal upon success, an error code otherwise

virtual OFCondition DcmDate::getOFString (  OFString &  stringVal,
const unsigned long  pos,
OFBool  normalize = OFTrue
)  [virtual]
 

get a copy of a particular string component

Parameters:
stringVal variable in which the result value is stored
pos index of the value in case of multi-valued elements (0..vm-1)
normalize delete trailing spaces if OFTrue
Returns:
status, EC_Normal if successful, an error code otherwise

Reimplemented from DcmByteString.

virtual DcmEVR DcmDate::ident (   )  const [virtual]
 

get element type identifier

Returns:
type identifier of this class (EVR_DA)

Reimplemented from DcmByteString.

DcmDate& DcmDate::operator= (  const DcmDate &  obj  ) 
 

assignment operator

Parameters:
obj element to be assigned/copied
Returns:
reference to this object

OFCondition DcmDate::setCurrentDate (   ) 
 

set the element value to the current system date.

The DICOM DA format supported by this function is "YYYYMMDD". If the current system date is unavailable the date is set to "19000101" and an error code is returned.

Returns:
EC_Normal upon success, an error code otherwise

OFCondition DcmDate::setOFDate (  const OFDate &  dateValue  ) 
 

set the element value to the given date

Parameters:
dateValue date to be set (should be a valid date)
Returns:
EC_Normal upon success, an error code otherwise
